Does anyone have any suggestions or tricks that ease the loading of 
thick, curled paper?

I've concluded a bunch of paper tests and settled on Photo Rag 308 as 
my 'stock' paper, and in order to have as great a variety of 
possibilies re paper size, I bought a 24" roll that I had cut up into 2 
smaller 
rolls of 11" and 13". Problem is, there is an inherent curl to the 
paper when I cut it down to size, which even a week's habitation in a 
mount press wouldn't straighten.

My problem is that the paper will simply not feed through my printers 
(a 1200 and a 2000P) without a great deal of fiddling, pushing, and 
frustration. It works OK in smaller size, 8.5x11 or less, but I have 
yet to get a sheet of 13x19 or longer through either printer. 

Was buying a roll a bad move, or is there some solution? Any 
suggestions would be greatly appreciated.
